Project: GDPR Alert [1] Version: 1.0.0 Date: 2023-June-28 Security risk: *Moderately critical* 11∕25 AC:Basic/A:Admin/CI:Some/II:Some/E:Theoretical/TD:Uncommon [2] Vulnerability: Cross Site Scripting

Affected versions: >=1.0 <1.0.1 Description:  This module enables you to define configurable GDPR alert messages.

The module doesn't sufficiently filter user-supplied text leading to a Cross Site Scripting (XSS) vulnerability.

This vulnerability is mitigated by the fact that an attacker needs additional permissions. The vulnerability can be exploited by an attacker with a role with the permission "administer gdpr alert" regardless of other configurations.

Solution:  Install the latest version:

* If you use the GDPR alert module 1.0.0, upgrade to GDPR alert 1.0.1 [3]
